Title: New basic organic complexes containing zinc
Inventor: TWITCHETT HARRY JAMES
IPC: C08G18/22
Filed: 1961-03-06
Abstract: The invention comprises co-ordination complexes of a zinc salt of an acid selected from thio- and dithio-phosphoric acids <FORM:0937882/IV(a)/1> thio- and dithiophosphinic acids <FORM:0937882/IV(a)/2> and thio- and dithio-carbamic acids <FORM:0937882/IV(a)/3> wherein R and R1 are hydrocarbon or substituted hydrocarbon radicals which may be the same or different, and X is oxygen or sulphur with a heterocyclic tertiary amine in which one N atom is common to two rings, or with a heterocyclic ditertiary amine in which the N atoms which may or may not be in the same ring are separated from one another either by two or three carbon atoms. The radicals R and R1 may be alkyl, cycloalkyl, aryl, or aralkyl or an alkyl group interrupted by one or more hetero atoms, e.g. oxygen or sulphur, or R and R1 may together form an alkylene radical which may be interrupted by a hetero atom such as O or S and which together with the remainder of the thio acid molecule will form a ring structure containing from 4 to 7 atoms in the ring, e.g. the radical -(CH2)4- or -CH2CH2OCH2CH2-.  The complex may comprise the combination of either (a) one or two molecules of the zinc compound with one molecule of the amine or (b) one molecule of the zinc compound with two molecules of the amine.  The complexes may be obtained by mixing together solutions or suspensions containing the appropriate molecular proportions of the zinc compound and the amine and if necessary heating the mixture under reflux.  Suitable solvents include acetone, petroleum ether, toluene and cyclohexanone. Specified tertiary amines are quinuclidine, 1:4-diaza-bicyclo-[2,2,2]-octane, pyrrolizidine, 7-oxal-1-aza-bicyclo-[4,3,0]-nonane and specified ditertiary amines are 4-dimethyl (or -di-n-butyl) aminopyridine, 4-morpholino pyridine, 4-pyrrolidinopyridine, N,N1-dimethylpiperazine, 1:10-phenanthroline, 2,21-dipyridyl and N,N1-dimethyl-1:4-diazacycloheptane.  In one of the examples given zinc diphenyldithiophosphinate is first reacted with pyridine to form a 1:1 molar complex and the latter is then converted to the 4-dimethylaminopyridine complex by reacting the pyridine complex suspended in dry chloroform with 4-dimethylaminopyridine.  The products are useful as antioxidants and as catalysts in the production of urethanes from organic isocyanates and hydroxy compounds.

Title: Improvements in the Manufacture of Narrow-mouthed Hollow Glass Articles and in Apparatus to be used therein.
IPC: C03B9/16
Filed: 1919-03-31
Abstract: 136,518. Naamlooze Vennootschap Glasfabriek Leerdam voorheen Jeekel, Mijnssen, & Go. Dec. 10, 1918, [Convention date]. Blowing.-In a non-automatic machine for making narrow-necked bottles, the parison and finishing moulds are arranged in pairs so that two bottles are blown at a time, the metal is forced down into the ring mould by compressed air, and the parisons are blown up against bottom moulds, or covers to the parison moulds, which covers also serve for the introduction of the compressed air into the parison moulds. The machine, as shown in Fig. 1, has parison moulds 3 and finishing-moulds A of the usual construction, except that each mould has spaces for the formation of two articles. The parison mould is recessed for the reception of ring moulds 10, Fig. 2, of the scissors type, and plungers 17, secured to a rod 19 and operated by a treadle 21, Fig. 1, enter through apertures in the table 1 to assist in the formation of the mouths of the bottles. A duplex blowhead 25 of any suitable construction is positioned above the parison mould. It is lowered on to the parison mould by a handle 26, and the arrangement is such that the blowing-head only acts as a mould cover until springs 27 are compressed, when air is admitted to the parison mould. In use, metal is dropped into the parison mould and the handle 26 drawn down to cover the moulds. Continued movement of the handle compresses the springs 27 and admits compressed air into the moulds so as to force the metal into the ring moulds. The handle is then raised: slightly to cut off the air supply, and the parisons are then blown up against the mould covers by air admitted to the ring moulds by a valve 24. Finally, the ring moulds and parisons are transferred by hand to the finishing-moulds for the completion of the bottles.

Title: An improved extrusion press for the manufacture of aluminium tubes, more particularly cable sheathings of aluminium
IPC: B21C31/00
Filed: 1953-03-25
Abstract: 738,514. Extruding. SCHLOEMANN AKT.- GES. March 25, 1953 [April 9, 1952], No. 8207/53. Class 83 (4). An extrusion press for making aluminium tubes, particularly for sheathing cables with aluminium, has two billet receivers 3, 4, with their axes disposed laterally to the axis of the extrusion die 1, for receiving billets 5c, 5b respectively, which are pressed by rams 6c, 6b, connected to hydraulic pistons 7c, 7b, and a throttle valve V for controlling the supply of pressure liquid to one piston 7c is controlled in dependence upon the speed of the other piston 7b so that the same quantity of aluminium is fed from both receivers. The billets are of equal cross-sectional areas and the piston 7c is larger in diameter than the piston 7b. Toothed racks 13, 14 connected to the rams 6b, 6c act upon coaxial pinions 15, 16 to which pointers 17, 18 are attached. When the speeds of extrusion from the two receivers are equal the pointers are in step but any deviation in speed causes one pointer to move ahead of the other pointer, thereby indicating the deviation to an operator who adjusts the throttle valve V accordingly. Alternatively the throttle may be operated automatically by electrical devices controlled by the pointers. In another embodiment the billets are of equal volume but different crosssectional areas and the hydraulic pistons are of equal diameter. Specification 702,505 is referred to.

Title: Machine for folding sheets, forms, and the like, and for inserting the folded matter into envelopes
IPC: B43M3/02
Filed: 1927-03-26
Abstract: 293,094. Thyme, L. March 26, 1927. Folding paper.-Paper sheets, forms, or the like are folded longitudinally and transversely by blades 4, 5, Fig. 2, which operate successively in planes perpendicular to each other and derive their motion from a common shaft 12 carrying a toothed segment 14 adapted to engage alternately two pinions 15, 16 operating the respective blades 4, 5. The blade 4 is carried by a cross-bar 22 moving in guideways 6 and conneced by a rod 21 to a crank disc 19 on the shaft 17 of the pinion 15. A bell-crank lever 25, 26 is forked at one end and connected to the blade 5 by pin-andslot arrangement, the other end of the lever being attached to a rod 24 on an eccentric 23 carried by the shaft 18 of the pinion 16. A sheet to be folded is placed on a table 2 against adjustable stops 30, 31 and the blade 4 folds it through a slot 7 into a guideway 11, Fig. 3, between the table 2 and a lower table 3. On the withdrawal of the blade 4 to its original position, the blade 5 is set in motion and folds the sheet through a slot 10 in the guideway 11. Behind the guideway 11, Fig. 3, is arranged a stack of envelopes with their flaps bent back parallel to the guideway and pressed forward by a member 39 against steel bands 40 so that the pocket 35 of the foremost envelope is opposite the slot 10. The blade 5, in its folding movement, inserts the sheet into the envelope and then carries the envelope and sheet with it until they are over a slot 33 in the table 3. As the blade 5 is withdrawn, a spring-controlled stripper 37 engages the angular part of the pocket 35 and prevents backward movement of the envelope with the enclosed sheet which drops through the slot 33 into a collecting receptacle. The pile of envelopes is pressed towards the bands 40 by the member 39 which is moved forward automatically by the engagement of a half-nut 52 thereon with a screwed spindle 48 operated through ratchet mechanism 46 connected to the shaft 17 by links 42, 43 and an eccentric 41. The nut 52 can be disengaged from the spindle 48, against spring action, by a handle 54.
